Su Yu explained how he could help the Holy Soul Grass quickly regrow its new body, but the Holy Soul Grass refused. 

The Holy Soul Grass had the ability to regenerate, but the process was fraught with extreme danger. Even in the Ice and Fire Yin Yang Well, there was a 30–40% risk of failure. 

Regenerating a new body would result in a decrease in cultivation level. 

However, for the Holy Soul Grass, which feared tribulation lightning, this ability was akin to a life-saving skill. 

When the heavenly tribulation was imminent, it would inevitably take the risk, but without the tribulation looming, it would avoid regeneration. 

After all, a 30% mortality rate was already too high. 

With Su Yu's ultimate life-protecting abilities, its survival rate was as high as 95%. The Holy Soul Grass naturally wouldn't refuse this opportunity. 

There might never be another chance like this in the future. 

By sacrificing some cultivation, it could extend its life by at least a thousand years—a trade too valuable to pass up. 

As for being transplanted outside the Ice and Fire Yin Yang Well, the Holy Soul Grass rejected the idea outright. Its growth environment was far too specific; outside the well, it couldn't survive. It would likely lose its spiritual vitality and soul before even facing the tribulation. 

"Alright." 

Su Yu had no objection to the Holy Soul Grass's request. After all, who wouldn't prefer a simpler solution? 

The Holy Soul Grass stood over a meter tall, emanating a faint, ethereal glow, and resembled an otherworldly bamboo shoot. 

When Su Yu first sensed its spiritual energy, he'd even considered absorbing it himself. 

Releasing his soul power, Su Yu infused it with an unparalleled life attribute. 

The soul power wrapped tightly around the Holy Soul Grass. 

The plant's spiritual energy began to converge. Shadows started appearing on the original body of the Holy Soul Grass, forming another Holy Soul Grass made entirely of spiritual energy. Slowly, this new form detached from the original body. 

In its soul state, the Holy Soul Grass remained relatively stable under the protection of celestial energy. 

Su Yu dug up its discarded body, clearing space for the regeneration of the new one. 

As the new body began to form, Su Yu's boundless life force was absorbed to nourish the "disembodied" soul of the Holy Soul Grass. 

For all living things, the growth of the physical body feeds back into the soul. For human soul masters, spiritual power grows in tandem with soul power for the same reason. 

Through Su Yu's immense life force, the Holy Soul Grass experienced rapid feedback, quickly forming a connection between its soul and the new body. 

"Alright, that's enough! Stop, no more!" The Holy Soul Grass cried out hurriedly once it had fully adapted to its new body. 

Su Yu promptly stopped the infusion of life force and closed his eyes to process his gains. The rebirth of the Holy Soul Grass gave him new insights into the cycle of life and death. 

In the sea of his spirit, the transition between the two runes of life and death became smoother. 

The green and gray lights emanating from the runes grew too bright to be obscured by the purple aura. 

The green and gray glows complemented each other harmoniously, transitioning seamlessly at their boundaries. 

"Can I have one of your seeds?" Su Yu finally asked the Holy Soul Grass for a seed. 

At the same time, he dug up several high-year medicinal herbs and left behind their seeds. Using his sixth soul skill, he rapidly nurtured the seeds before departing from the Ice and Fire Yin Yang Well.

*Ten Days Later* 

*Demonic Forest* 

"Xiao Yu, you're back?" Xuan Ziwen exclaimed with surprise and delight. 

Kong Deming had already located their target early on. He was now keeping watch over the Demonic Eye Tyrant, while Xuan Ziwen waited outside the Demonic Forest for Su Yu's arrival. 

"Yes, Senior Brother. This is the Holy Soul Grass. Eat it fifteen minutes before you absorb the spirit ring." 

The Holy Soul Grass's soul had successfully merged with its new body, leaving a substantial amount of spiritual energy in its essence. This provided significant benefits for enhancing spiritual power. 

Most importantly, the medicinal properties of the Holy Soul Grass could improve a soul master's innate talent in spiritual power. 

Su Yu didn't accompany Xuan Ziwen into the Demonic Forest. Instead, he found a secluded spot outside the forest to wait for good news from the two of them. 

Although Su Yu's strength surpassed his senior brother's, facing the Demonic Emperor would only hinder their efforts. It was better for him to stay out of the way. 

"Holy Soul Grass"

Su Yu's Experiment with the Seed

Su Yu gazed at the seed in his hand, pondering the possibility of creating a soul beast born from his imagination. 

Infusing it with the ultimate vitality, he watched as life began to sprout. 

*Boom!* 

From within the Demonic Forest, an earth-shaking explosion erupted. 

Even Su Yu, positioned outside the forest, could feel the ground tremble violently as chaotic elemental energy surged. 

An overwhelming wave of spiritual energy radiated outward. 

Under its influence, most creatures within the Demonic Forest and its surrounding area instantly fell unconscious. 

In Su Yu's sea of spirit, the runes for "Condense," "Converge," and "Protect" flashed brilliantly, guarding the space securely. 

At the same time, the "Sword" rune unleashed its power, concentrating Su Yu's spiritual energy into a sword aura that slashed through and neutralized the impact. 

"What overwhelming spiritual energy." 

It had to be the Evil Emperor. 

Su Yu's expression grew heavy as he turned his gaze toward the depths of the Demonic Forest. 

The intensity of this spiritual energy placed it among the strongest below the Divine Origin Realm for human soul masters—what Kong Deming referred to as the Spirit Domain Realm. 

The Spirit Abyss Realm, originally the highest classification for spiritual power established by the researchers of the Sun-Moon Hall's spiritual energy detection instruments, was surpassed by the Spirit Domain Realm according to Kong Deming's later refinements. 

These divisions matched what Su Yu remembered from the original story, set ten thousand years in the future. Beyond the Spirit Abyss Realm was the Spirit Domain Realm, where spiritual energy began to materialize. 

The Spirit Domain Realm signified the initial stage of spiritual energy becoming tangible. 

Su Yu's spiritual power had reached the peak of "form without substance," a hallmark of the Spirit Domain Realm. 

Yet, this was only the entry point. 

Based on Kong Deming's teachings and Su Yu's own memories, the true defining feature of the Spirit Domain Realm was when spiritual power advanced to "form with substance," completing its materialization. At this stage, a soul master could shape their spiritual power into a domain centered around their soul, creating an independent world. 

If fortunate enough to awaken their innate potential, a soul master could solidify this into a unique spiritual domain akin to a martial soul domain—an ability rooted in their very essence. 

Judging by the Evil Emperor's spiritual fluctuations, Su Yu deduced that it had already reached the "form with substance" stage of the Spirit Domain Realm. 

The constant spiritual energy surges were not entirely detrimental to Su Yu. 

After enduring the first wave of spiritual impact, Su Yu chose to lower his defenses around his sea of spirit. 

His eyes lit up with determination. 

Channeling his spiritual energy into the "Sword" rune, he activated his fourth soul ring, which seemed to resonate with the rune. 

At this moment, Su Yu's spiritual energy transformed completely into a sword, enduring the Evil Emperor's spiritual assaults like a blade of sword grass. Gradually, it grew more solid and refined. 

Just as the sword grass tempered itself under relentless trials, Su Yu used the Evil Emperor's spiritual energy strikes to push his own spiritual energy toward a breakthrough. 

Deep within the Demonic Forest, the enraged Evil Emperor seemed to sense the powerful spiritual presence resisting within its domain of influence. 

"Hmph!" 

Su Yu's face turned pale as the Evil Emperor's spiritual energy coalesced into a ferocious surge, directly targeting him. 

In his sea of spirit, emerald light radiated as the life essence of the Blade of Life—sealed by Electrolux—repaired his damaged mental space. 

Su Yu felt like a fragile blade of grass battered by a relentless storm. 

Yet, no matter how fierce the winds and rains, he clung steadfastly to his roots, drawing upon the life essence. As his will grew firmer, the vitality of the grass only flourished. 

*Boom!* 

It was as though a barrier shattered—Su Yu's spiritual energy rapidly condensed. 

His spiritual power took on the form of a small blade of grass, tenaciously rooted within the crashing waves of the Evil Emperor's spiritual onslaught. 

Form with substance.
